PREPARING FABRICS FOR PRINTING.

Specification of Letters Patent No. 5,480, dated March 21, 1848.

T all whom it may concern Be it known that I, JOHN Coi-vries, ofManchester, in the county of Lancaster, England, a subject ofthe Queenof Great Britain, have invented certain improvements in machinery orapparatus for cleaning the surface of woven fabrics or freeing the samefrom fibrous or other loose matters previous to printing thereon; and Ido hereby declare that the following is a full and exact description ofmy said invention-that is to say, these improvements in machinery orapparatus for cleaning the surface of woven fabrics o-r freeing the samefrom fibrous or other loose matters previous to printing thereon consistin the application, employment, or use for such purposes of a revolvingcylinder or roller covered with wire cards, such as is used in thecarding of cotton, either employed in connection with a stationary brushor without it, which apparatus may be either attached to the ordinaryprinting-machine for printing calicos or other woven fabrics or to thewinding-machine for preparing the cloth-roller used in such machinery orused separately from either.

This apparatus is to be applied to the surface of calico or any wovenfabric to clean itfro-m loose fibers or other extraneous mattersprevio-us to printing thereon and thereby preventing` the occurence ofimperfect work frequently arising from the presence of such loosematters and also increasing the capability of producing more work in agiven time. Such card cylinder or roller and brush or any othermodification of a similar cleaning apparatus may either be usedseparately or detached if preferred or may be attached to or inconnection with the ordinary calico printing machine as herein describedand placed between the cloth roller and the printing roller or it may beemployed in any other convenient situation.

In the drawing accompanying these presents Figure 1 shows a plan view ofan arrangement of mechanism which is suitable to the above purposes anddrawn upon a scale of about two inches to the foot. Fig. 2, is an endview and Fig. 3, a section of the same. Fig. 4, is a diagram showing therelative position of the apparatus when used in connection with theordinary calico printing machine.

The cloth or calico is represented by the red line.

a, a, is t-he side framing of the apparatus connected together by therods o, and supporting the tension rail c, c, under which the clothpasses and thence over the stationary brush cl, CZ, which has a doctoror steel blade e, e, extending along one side. The cloth then passesover the wire card cylinder or roller f, f, and over the tension rollerg, g, to the printing apparatus. The roller g, g, may be covered withfelt or cloth if preferred and the tension of the calico or other wovenfabric passing over it causes the same to revolve and by means of thespur pinion h, and wheel z', turns the wire card cylinder or roller f,f, in the reverse direction. Thus the calico or other woven fabricpassing over the stationary brush (l, d, and doctor e, e, andsubsequently over the revolving card cylinder or roller becomesthoroughly brushed and cleaned from any loose material which mightadhere to it thus causing the fabric to present a much smoother orbetter surface for printing. The brush el, cl, and the wire cardcylinder or roller f, f, may be adjusted by the screws 7c, 7c, and aslight lateral or traversing mot-ion may also be imparted to it perhapsin some instances in an oblique direction to that of the cloth.

hen the apparatus is not desired to be at work the tension rail 0, c,may be thrown into the position shown by dotted lines at Fig. 3 by meansof the lever Z, the cloth will then pass over the roller g, g, withouttouching the brush or the said card cylinder or roller.

I claim- The use of a. card cylinder and brush as applied to theordinary calico printing machine for cleaning the surface of the clot-has described.
